From September 30 to October 13, 2023, the Kyiv International Institute of Sociology (KIIS) conducted an all-Ukrainian public opinion survey "Omnibus", which included a question about the feasibility of criticizing possible wrong decisions of the authorities now. Bythemethodofcomputer-assistedtelephoneinterviews(CATI) based on a random sample of mobile phone numbers (with random generation of phone numbers and subsequent statistical weighting), 2,007 respondents living in all regions of Ukraine (except the AR of Crimea) were interviewed. The survey was conducted with adult (aged 18 and older) citizens of Ukraine who, at the time of the survey, lived on the territory of Ukraine (within the boundaries controlled by the authorities of Ukraine until February 24, 2022). Residents of temporarily occupied territories could not be included in the sample, and the survey was not conducted with citizens abroad.

Formally, under normal circumstances, the statistical error of such a sample (with a probability of 0.95 and taking into account the design effect of 1.1) did not exceed 2.4% for indicators close to 50%, 2.1% for indicators close to 25%, 1.5% - for indicators close to 10%, 1.1% - for indicators close to 5%.

Under conditions of war, in addition to the specified formal error, a certain systematic deviation is added. However, despite certain factors that may affect the quality of the results in "wartime" conditions, in general, we believe that the obtained results still retain a high degree of representativeness and allow a fairly reliable analysis of the public mood of the population.

Also, the press release compares the current mood of the population with the mood of the population as of May 2022 (according to the results of a survey conducted by KIIS on May 23-27, 2023 and in the framework of which 1,201 respondents were interviewed by the method of telephone interviews).
